Abstract :
We propose a novel scheme to perform an optical multicast overlay on a survivable wavelength division multiplexed passive optical network. By flexibly controlling a sinusoidal clock signal and an optical switch at the optical line terminal, optical sub-carriers, which enable not only protection for distribution and feeder fibers, but also multicast data delivery, are generated. 10-Gb/s transmissions under both normal working and protection modes are experimentally demonstrated.
